`specification forming part of Letters 13u-tent No. 16.462,'dated JannaryQ?, 1857-.

To all whom 'it may concern:

Be it known that I, SAMUEL BRADBUEY, of Griggsville, in the `countyof Pikeand State of Illinois, have iiiventeda new and Improved Mode of .l`rim mingHedges; and I do hereby de- Figure l represents atop vie'w of the ma-y machin, reference being also had to the dil'erent parts of the invention represented in the drawings by letters. I construct a frame carleft of the carriage is xed a cogged driving iront, which pinion is placed on the end of a shaft, F, that rests upon two arms, Gr, arranged l is fixed asecondJlrivingwheel, H, With heve1-cogs on the side and square cogs on the end.l The side cogs meshes ina beveled pinion,".I, which rests on the main axle J ofthe ning across the axle J near its bearing. It is,

an iron rodL, which rod is also attached length, which beam is hung upon a hinge, N, and isso constructed that the out endiseasily raised or lowered and made irm at any given height, from o ne toot to tive feet, or more, if required, fromthe ground, by a gage, Z,

works freely in every position. There are two ary, while the other part works freely.' rlhe moving knife M-is supported by strong iron clasps P, under which it plies. The knife M also serves to hold the brush while being out. The edge-cogson the driving-wheel H also drives another. square pinion, Q,- placed under the beveled wheel J, topwhich is attached a shaft, R, extending parallelwith the main axle J to a post, S, which ,rests on the right end' of the axle J'. Onthe shalt R isa crank, T,

to whichis attached van iron arm, U, extend-v ing nearly to the top of Vthe` post'S, Which-is also attached to another sliding knife-or cnt'- ter, B B, which plies through iron fingers V,bu t

nearly'in a perpendicular position. `This ary rangement is intended to trim the side of the hedge, While thefm'ova'ble beam- A and knife or cutter M will ent the topat any stage from its iirst start to-a full' g'rown'he'dge. The right-l hand wheel, G, of the carriage is placed a littlel back ofthe right end ot' the main axle J, between two'arms,W arranged for that purpose. There is also a circling brace, X, which 1s made fast to the out end ot' the arms Wand to the' top end of the post S, also, another brace, Y,

made fast nearthe bottom of the circling brace` X, which supports the elevated beam A. I

also place a tongue, A A, in front on the right of the second driving-wheel, [La little past the center toward the left, which leaves room forthe od horse between the tongue and the hedge. f

C C represent a beam, and D D ashaft, which was intended as a mower or grass cut-l ter, but is notconsidered as a partot this speciiication.-

Operation: My machine is drawn by tivo horses, and is driven along the side of the hedge, while theknives ply freely, the up-and' down knives .trimming the side' of the hedge, While the knives on the elevated beam plies at the same time, cutting the top ot the hedge,y sloping up, then driving 'upon tlre other side of the hedge, trimmngit in' the same manner,`

which completes thetrimmiug and leaves thev top ofthe hedge roofing and a little the Widest at the bottom.'

What I. claim as my invention, and desireto secure by Letters Patent, is

The arrangement of the adjustable cutters M and vertical cutters B B, operated in the manner and for the purposes herein set forth.
